A comprehensive roadmap describing the current density- and size-dependent dendrite growth mechanisms is presented. Based on a thermodynamically consistent theory, the combined effects of chemical diffusion, electrodeposition, and elastic and plastic deformation kinetics are analyzed to rationalize their contributions to experimentally observable morphologies. A critical current density, \u00ee<\/em>* = z<\/em>\"F\"i<\/em>lim<\/sub><\/small>l<\/em>(\u0394G\u03a9\u03ba<\/em>i<\/em><\/sub><\/small>), in the t<\/em>\u03c3<\/em><\/sub><\/small> < t<\/em> < t<\/em>Sand<\/sub><\/small> range, results in plastic flow at the tips, dendrite bifurcation, and bent and kinked morphologies. Three dendrite growth mechanisms are observed: (1) electrochemical shielding, where there is practically no electrodeposition\/electrodissolution; (2) stress-induced electrodissolution and electrodeposition on those interfaces directly facing each other, generating a self-sustained overpotential that pushes the dendrites towards the counter electrode; and (3) local, lateral plastic extrusion in those side branches experiencing non-hydrostatic stresses. Six regimes of lithium electrodeposit growth are identified: (i) thermodynamic suppression regime, (ii) incubation regime, (iii) base-controlled regime, (iv) tip-controlled regime, (v) mixed regime, and (vi) Sand’s regime.<\/p>\n
